Twenty years after it swept Australia into the international film spotlight, Peter Weir’s stunning 1975 masterpiece remains as ineffable as the unanswerable mystery at its core. A Valentine’s Day picnic at an ancient volcanic outcropping turns to disaster for the residents of Mrs. Appleyard’s school when a few young girls inexplicably vanish on Hanging Rock. A lyrical, meditative film charged with suppressed longings, Picnic at Hanging Rock is here available in a pristine widescreen director’s cut with a Dolby digital 5.1 channel soundtrack.
